Non-Feature Class Issues
FDOClass
This class is used for non-spatial data. It can act as a stand-alone class, where it would have no association with any other class, or if the FdoClass is being used as an ObjectProperty, it can be used to define properties of some other FdoClass or FdoFeatureClass.
ObjectProperties have the following types:
- Value
- Collection
- OrderedCollection
The Value ObjectProperty type has a relationship of one-to-one, providing a single value for each property.
The Collection and OrderedCollection ObjectProperty types have a one-to-many relationship, where many ObjectProperties may be associated with one property. Ordered Collections can be stored in an ascending or descending order
At least one Identifier will be required if the FdoClass is to be used as a stand-alone Class.
- All Identifiers for FdoDataType_Int64 must not be Read-Only, since none of these will be an auto-generated property value.
- If creating multiple Identifiers, all Identifiers must be set to NOT NULL.
